New mag with non-consistant fire

[sasquatchrt]

I purchased an automag rt ule and when i first screwed in my tank it wouldnt fire. there was only enough pressure to push the trigger forward into place again. no bolt action. i thought i had a low pressure output tank (450psi) and waited till i could try my friends who i knew was high output (800psi). however upon screwing his in, same thing, slight pressure in trigger, nothing else. so the tank was not the problem.

i called agd and he could only suggest a few minor things.. and what made it finnaly fire was simply adding some oil into the bolt... however

it will fire when i first screw in the tank, i can get some shots off, about 5-20 and then it will stop firing and do the same problem where only the trigger moves forward, but no bolt action. sometimes after some pulls of the trigger it will start to fire another chain, but not long. when i take the tank off and put it back on, it will fire, but only for those few shots. it also leaks air out the front of the bolt too sometimes when im shooting/trying to shoot.


when i hung up the phone with the man from agd i thought it was working fine, plus i was late for work. so we both thought the problem was fixed, however he suggested if the problem ever arose again, which it did real fast, that i (can't remember exactly what he said) take apart the lvl 10 and and i believe replace the carrier piece with the black o-ring around it with the next size up? i'm not sure exactly until i call back again tomorrow..

any suggestions?

------------------------------------------------------------------------------

Alright, i exchanged the carrier, it was the one dot, and i put the next size up (to my knowledge), the one line in, and used the same white o-ring. and it still is having problems. it will shoot, but then some pulls of the trigger the air leaks out the front of the bolt, to me it seems like the lvl 10 is reacting as if something was blocking it, but it still has a good bolt action. other pulls is does nothing at all, the trigger just goes loose.

does the new carrier need to be worked in? is there any tuning i need to do to the lvl 10? would it have anything to do with the ULE trigger?

here is a video of what is happening: http://www.youtube.com/watch?v=uv7jRFXzK-w


the quick short sounds are the bolt firing properly, the slightly longer hissing sounds is the air coming out of the front of the bolt, and then you can see the times when i pull the trigger and there is no reaction at all. also sometimes it would take a slight second longer for the trigger to be pushed forward into position. then after those first initial shots that work and hiss, it will stop reacting altogether and the bolt does nothing.

and if you're wondering why i'm in a car, i live in an apartment and my step-dad thinks the other people will get mad if i fire inside..

-----------------------------------------------------------------------------

hopefully last problem to deal with..

i called agd because even after switching the carrier it still was not working, as shone above. he told me to replace the white carrier o-ring, which i did and shot it a good amount of times to work it in. the gun is shootin alot better, no more air leaks or non-responsive triggers,

however, it seems to happen when tryin to walk the trigger, their will be a small hissing sound and the trigger has not fully pulled forward into position, and once the hissing stops the trigger immediately responds and pulls forward again so i can shoot it. otherwise if i pull the trigger while the hissing is around it does nothing.

does this hav anything to do with the shims? i have my one chance to call agd between school and work tomorrow, otherwise i hav to wait till monday since that will be the next time their open.

again, any suggestions? thanks abunch

Change to the next loosest carrier while still using the same carrier o-ring. Also take a look inside of the body where the valve goes into. Is there any heavy wear marks/groves at the inside top?

[sasquatchrt]

no there is not wear inside the body. and how do i get the carrier out? what type of tool should i use cuz i dont see it being to easy to do.

Unscrew the bolt tip to remove the carrier. Good next size up on carrier. Mags like lots of oil.

[sasquatchrt]

no sorry, i kno how to get down into the bolt, i jus dnt kno how to extract the carrier from inside the the bolt

and i hav 3 extra carriers it comes with one without a groove and two with the same groove, im pretty sure the more grooves the bigger the carrier, so are those other two the same size?

[flyingpootang]

Remove the top with a 3/8" wrench, remove the shims (if any) use a ball tipped allen wrench to pull out the the carrier. The carrier sizes go from small to large with blank, 1 dot, 1 line, 1 dot 1 line, 2 lines, 1 dot 2lines, etc.... Just make sure to use the same white carrier o-ring. If not then you have to re break in the o-ring

[Me�iCX]

Dental pick works good for pulling out the carrier. Just be careful not to tear or cut the carrier o-ring.

[punkncat]

The valve strip screw works great for pulling carriers. Just ever so slightly and gently start threading it into the carrier until it starts giving resistance and pull up.

i replaced the carrier. please read the edit on first post ^ thankyou

You want the largest carrier that doesn't leak. Keep moving up in half sizes until it leaks, then move back down half a size.

If you have a ULE trigger kit in there, take it out until you get your LVL 10 tuned.

LVL 10 quick tuning:
Follow these steps in order.
1. Break in carrier o-ring with 1000 shots in carrier #2 (2 lines, no dots on side of carrier).
2. Move broken-in white carrier o-ring to largest carrier that does not leak.
3. If bolt sticks on squeegy test, add shims until it resets reliably.
4. Chrono marker to field speed. (this is important, don't just do it by sound)
5. If gun breaks paint (test with no loader and make an electrical tape string for paintball to hang only halfway in breach) use a longer mainspring (on the contrary, if bolt continuously "LVL 10's" or "chuffs" use a shorter mainspring).

read latest edit on first post please.. and thanks very much to those who have been replying.

[secretweaponevan]

I see you moved up a half-size on your carrier. That may not be big enough.

Take out any LVL 10 shims until after this next part.

After a break in of 1000-2000 shots (turn down the velocity to save air), move your white carrier o-ring to larger and larger carriers until you find one that leaks. Then back it down a half-size. After this is done, you may add 1 shim at a time if the bolt fails to reset after encountering a jam.

Do you have a ULE trigger kit in there?

[sasquatchrt]

Yea the ULE trigger was installed when I ordered the gun

[flyingpootang]

From the vid it looks like your velocity screw is screwed too far out, do you have more than 850 psi left in the tank? Is your ball detent screwed in to far? try and remove it and fire the marker again. Don't worry we'll get your mag running....

[secretweaponevan]

Yea the ULE trigger was installed when I ordered the gun

Ok then.

After you have the largest carrier that doesn't leak, use the bolt spring that allows the marker to fire at about 20 fps lower than your desired velocity.

Yes you will need a chrono for this. Yes this is important. If you have too strong a mainspring and your velocity is set too low, your marker will behave exactly as it does in your video. You have to do this after you break in a carrier o-ring and find the largest carrier that doesn't leak.
